Which of the statements is true about the graphed triangles?

• They are similar, because the image can be obtained by dilating about the origin with a scale factor of 2.

• They are similar, because the image can be obtained by dilating about the origin with a scale factor of 1/2.

• They are not similar, because the image can be obtained by dilating about the origin with a scale factor of 2.
